"When we've finished the current tour I'm going to go back to Italy and see if I can do some more writing"

Gerry Mulligan's quote recommends that he is anticipating completion of the current trip and going back to Italy. He is most likely excited to return to his house nation and to his writing. Mulligan is a prominent jazz saxophonist, author, and arranger, so it is most likely that he is describing writing music. He may be aiming to make up new pieces, or to set up existing works in a brand-new way. He may also be looking to write about his experiences on tour, or to write about jazz in basic. Whatever the case, Mulligan is clearly thrilled to return to Italy and to his composing. He is most likely eagerly anticipating the imaginative freedom that includes having the ability to write without the pressures of touring.
